Experts say that more than 1 billion young people cannot hear well.

They are between 12 and 34 years old. Young people often hear a loudcontinuous noise in their ears. Their hearing tests look normal. Later， their hearingtest results are worse.

Experts know reasons why this situation happens. Young people listen to theirheadphones. They also go to concerts. The music is too loud. Sometimes， music inrestaurants is loud， too.

Decibels1 tell us how loud something is. The sound of a food mixer is 85decibels. The sound of a train is 100 decibels. Experts say that it is safe to listen to85 decibels at work.

Sometimes we can lose hearing when we hear something very loud only once.Loud noise kills the cells2 in our ears. We cannot fix the situation.

專家表示，超过10 亿年轻人听力不好。

他们年龄在12 到34 岁之间。年轻人耳朵里经常听到连续不断的巨响。他们的听力测试看起来正常。后来，他们的听力测试结果变差了。

专家们知道这种情况发生的原因。年轻人用耳机听音乐，他们也去听音乐会。音乐太吵了。有时，餐馆里的音乐也很吵。

分贝告诉我们声音有多大。食物搅拌器的声音是85 分贝。火车的声音是100 分贝。专家表示，工作时听到85 分贝（的声音）是安全的。

有时，我们只听到一次非常响亮的声音也可能会失去听力。巨大的噪音杀死了我们耳朵里的细胞。我们无法解决这个问题。
